SCM SCR3311 USB 1.1 Smart Card Reader
The SCM Microsystems SCR3311 is an external USB 1.1 smart card reader designed for secure authentication and transaction processing. It features a single slot supporting ISO 7816 Class A and AB cards with sliding contacts rated for 100,000 insertions. The device is fully PC/SC and EMV Level 1 compliant with CCID support.

Preguntas sobre este artículo
Do I need a free USB Type-A port on my computer for the SCR3311 reader?
Yes, the reader connects through a USB Type-A plug and draws all of its power from the bus, so a spare port is the only requirement.
Will the SCR3311 work through a USB 2.0 or 3.0 hub that I already use?
The device is a USB 1.1 full-speed peripheral; it will enumerate on any newer hub or port, but the link will run at the 12 Mbps rate of the original interface.
How can I confirm the reader is communicating with a smart card after I plug it in?
The single green LED on the front changes state when a card is inserted and the PC/SC driver establishes a session, giving a clear visual indication of activity.
